Abstract

Current meter Nortek Aquadopp data. Data for 2 current meter deployments of NORTEK Aquadopp instruments at the Rainbow Massif. Instruments where kindly provided by the Parc National d'Instrumentation Océanographique de l'INSU.

Data is provided in 2 sets of files, corresponding to deployments AES_C01 and AES_C02. The instruments where installed in a broadband OBS (BBOBS) from the INSU OBS National Park.  Deployment AES_C02 includes two lowerings (see information below, indicated as deployments AES_C02A and AES_C02B).

AES_C01 with current meter serial number : A6L6094 (head) AQD11097 (Hardware), deployed on BB03 with deployment AES_B01_BB3. Bottom position: 36.23544°N, 33.91036°W, 2505 m waterdepth.

AES_C02_A with current meter serial number : A6L6127 (head) AQD11247 (Hardware), deployed on BB02, deployment AES_B03_BB02. Bottom position: 36.22233°N, 33.87996°W, 1950m waterdepth.

AES_C02_B with current meter serial number : A6L6127 (head) AQD11247 (Hardware), deployed on BB02, deployment AES_B06_BB02. Bottom position: 36.2020833°N, 33.8118833°W, 2557m waterdepth.

Data are provided in two zipped files that include:

AESC0101.aqd: Aquadopp binary file

AESC0101.dat: Ascii table of data - full record

AESC0101.dia: Aescii data file - partial record

AESC0101.hdr: Instrument parameter information and description of columns in AESC0101.dat

AESC0101.mat: Matlab file corresponding to AESC0101.dat

AESC0101.ssl: Log of instrument (error and info messages)

In addition to several instrument logs:

AESC01_start.log

AES_C01_deploy.dep

AESC01_start.dep

The ascii file contains 27 columns as follows:
